BOOT CAMP Option

This course is the last two days of BOOT CAMP.

BOOT CAMP is a full week of training for non‑engineers, covering the whole telecom and networking picture from fundamentals to future trends.

The week begins with three days of core training: The PSTN, wireless telecom, data communications, the Cloud, Ethernet and LANs, IP and networking, MPLS, and the Internet. On Thursday and Friday is this course: Voice over IP, SIP and SIP Trunking, VoIP systems, Security, and finishing with upcoming technologies, including 5G wireless and the Internet of Everything: how everything from toasters to self-driving trucks to human brain implants will be online.

Save $395: BOOT CAMP is only $1995 for the full week, a $395 savings. You may register for just the first three days (Course 101) or just the last two days (Course 130) as best meets your needs. But with the BOOT CAMP price savings of $395 compared to individual courses and wall-to-wall training, BOOT CAMP is a great opportunity.

1. VoIP Components, Systems, Standards, Jargon and Buzzwords

We will start with VoIP jargon and buzzwords, basics of communicating voice in IP packets, what the components of VoIP systems are and what each does: soft switches, media servers, gateways and terminals, plus the main standards and protocols used in VoIP systems. The last lesson is "where this is headed", what will people have as basic "telephone" service 50 years from now.

The Big Picture

VoIP System Components

Terminals

2. VoIP Architectures and Implementation Choices

"Voice over IP" can happen in many different ways. One by one, we'll review the many flavors of VoIP, comparing and contrasting the various implementations and architecture choices. Starting with different flavors of Internet telephony, we will then understand VoIP at the telephone company, how it merges with the existing base, and the new services like SIP Trunking. We will compare and contrast choices for a VoIP system: getting it from the phone company; buying a Call Manager / softswitch; renting a Hosted PBX; and Softswitch as a Service / Cloud solutions. You'll gain the knowledge to confidently differentiate VoIP architectures and discuss pros and cons of options.

Internet Telephony: Computer-Computer VoIP over Internet. e.g. Skype

VSP: Internet to Phone, e.g. Gmail "make a call", Hangouts dialer

VSP: Phone to Phone over Internet, e.g. Vonage

3. SIP and Call Flow in the IP World

SIP is the open, standard protocol for setting up Voice over IP telephone calls. All VoIP systems that purport to be "compatible" must adhere to the Session Initiation Protocol. It defines the procedure and messages to set up a phone call – or any other kind of communication. In this chapter, you'll understand what SIP is, how it works, demystify jargon like proxy server, registration and location server, understand how SIP fits in with softswitches and call managers, and trace the establishment of an IP phone call step by step. At the end of this, you'll understand call flow in IP telephone systems – maybe worth attending the course all by itself!

We'll begin MPLS, used by carriers for traffic management, as a Quality of Service (QoS) mechanism to meet Class of Service (CoS) performance guarantees in Service Level Agreements (SLAs). We'll sort out VPN backbones vs. Internet VPNs. You'll learn about native VoIP services from carriers, and the significant savings in costs compared to connecting at the DS0 level. We'll finish with legacy system integration. The final three lessons are bonus detailed reference material for those who need it.

We'll begin with an overview, then identify the valuable targets. Next, we'll explore the measures taken and best practices in the different areas of security – network security: filtering and firewalls; computer / operating system security: passwords, viruses, PCI compliance; information and communication security: public and private key encryption, digital signatures, digital certificates, IPsec; application security – examine an attack from the web to an SQL database step-by-step; and finally voice and video over IP security, including how yes, your microwave oven could be watching you.

Second up is the IoT. Non-technical people who write articles have been using the term "Internet of Things"… but this is missing the bigger picture. In the future, EVERYTHING will be connected, the Internet of Everything. We'll identify things that will be connected, then split into groups to identify the associated benefits and risks, and who is going to make money. Then we'll cover some practical issues: discussing how everything can get a computer, an operating system and an application inside it, plus a communication link… and power. We'll finish off with medical applications, home automation and the Software Defined Telecom Network.
